• Synonyms: 8-Methoxy-1',3',3'-trimethylspiro[1(2H)-benzopyran-2,2'-indoline]
• Melting Point: 124 °C
• Solubility: Solubility (slightly sol. in): Ethanol
• Appearance: White to Light yellow to Light red powder to crystal
• Application: Photochromic materials are further developed for a light-modulating materials, optical recording media, optical switches, and functional inks.
• Features And Benefits: A structural isomerization during photochromism involves photo-induced geometrical isomerizations and photo-induced ring-opening and -closure reactions. Fischer et al. first reported the photochromic behavior of spiropyrans. UV irradiation to a spiropyran undertakes a ring-opening of the spiro carbon. The structural change leads to a blue shift of photo absorption up to the visible region.
